DUAL ARCHITECTURE FOR AN ELECTRO-HYDRAULIC DRIVE SYSTEM, MACHINE AND METHOD FOR CONTROLLING A MACHINE WITH AN ELECTRO-HYDRAULIC DRIVE SYSTEM
An example hydraulic system includes a hydraulic actuator; a pump driven by an electric motor and having an inlet port and an outlet port; a boost flow line configured to provide boost fluid flow or receive excess fluid flow; a reservoir fluid line fluidly coupled to a reservoir; and a valve assembly configured to operate in a plurality of states to allow the pump to operate in a closed-circuit configuration in which fluid discharged from the hydraulic actuator is provided to the inlet port of the pump or an open-circuit configuration in which fluid discharged from the hydraulic actuator is provided to the reservoir.
